Write the name of the linkage joinining two amino acids.

Explanation

To answer the question about the linkage joining two amino acids, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components**: Understand that amino acids are the building blocks of proteins. Each amino acid has an amino group (-NH2), a carboxyl group (-COOH), and a unique side chain (R group).

2. **Understand the Reaction**: When two amino acids come together, they undergo a condensation reaction (also known as dehydration synthesis) where a molecule of water is removed.
